- Abstract
The transurethral resection of the prostate (TUR-P) is an endoscopic technique and the gold standard for the surgical treatment of benign prostate hyperplasia (BPH). It remains unclear if there is the possibility of electrothermal injuries of tissue which is not directly treated during bipolar TUR-P. The reason could be higher generator output powers of bipolar systems. Therefore, measured values of the power loss density distribution around a bipolar resectoscope are used as source term for the calculation of temperature changes in tissue not treated directly. The temperature calculations are based on the numerical solution of Penne's bioheat equation. With the chosen boundary conditions and input parameters no significant increase of temperature is found in the calculation domain at the proximal end of the resectoscope shaft. For a comprehensive understanding further investigations will be carried out with different boundary conditions and input parameters.
